China has won approval for seven international natural gas standards it is leading, according to the State Administration for Market Regulation.

The standards were given the green light by the International Organization for Standardization, covering key upstream areas of the industrial chain including shale gas exploration and development, natural gas carbon footprint accounting, natural gas reservoir core sampling and natural gas hydrate testing.

The move will help build a globally unified set of technical rules for natural gas and advance the development of a clean, low-carbon, safe and efficient global energy system.

Among the approved items, three shale gas testing standards will provide a unified technical basis for unconventional oil and gas development, filling gaps in shale gas reserve evaluation and engineering safety specifications.
